hi all, I would like to know if anyone knows how to mount the dropouts that are under the engine of Rumi. thank you. I have the engine already mounted on and I can not synchronize everything again! is there a trick? thanks Federico. I write with the translator, I hope you all understand what I mean. sorry.

I understand looking at your photos that you have remove the little plate that is under some Rumi engines (not all Rumi engines has that cover). UUufff, I have never seen anybody removing that cover with the rest of the engine assembled.

The logical way (under my point of view), is to build the engine in the other way around. So, with the lower half of the crankcase on the table (including this little plate in position), the rest of the parts have to be put in place, from bottom to up. (Gears, drum selector, etc). Once you have all in place you can check that all gears engage properly while turning the drum selector. Then closing the engine with the upper half of the crankcase (after adding sealant compound), then put the bolts to join both halves.

Removing the little plate as you did, is something that I would never do, but this is only because I have never work on a Rumi engine with that plate on it, so I have learn to do things in a different way.

Maybe somebody that have work with an engine like yours can give you instructions to how to set the gears and drum selector in an specific position that allow you to put the cover back in place in an easy way.

I know you use a translator, so maybe the translation is not good, but if what you are asking is how to put that cover again in place, as mentioned, probably there must be an easy way to do it setting the gears and drum selector in certain positions, hopefully somebody can tell you. HOWEVER if what you want is to replace the gear selector ... Why?, everything look good there. No parts look worn or damage. Why you want to replace it?

I made this mistake many years ago, like you I went crazy, after many unsuccessful attempts to align the bottom plate and the selector arms and forks with the gear slots, working from underneath the engine.

You have two solutions. Firstly, removing the engine, taking it apart and assembling it again after installing the plate and selectors. Hell on earth!!

Secondly, I promise you that it works, is to invert the machine, yes upside down. Insert the forks, upside down in the appropriate gear and selector drum slots. Now, as the plate has the long spindles which you can easily get at, it is straight forward to insert them in the appropriate holes in the selector arms and fit the base plate.

Do have somebody with you helping steadying the machine. A friend would appreciate a couple of beers, or your wife a slap up candlelit dinner!!

no replace it but reposition it, so that it works and inserts all the gears, not just second and third

4th gear stuff does not apply to your problem, that is external to the gearbox.

Providing that you position the selector forks in their correct respective gear slots and using your fingers to engage the base plate spindles in the holes in the selector arms and align the selector drum, everything will be ok.

thanks for warning me! I'll try to put the inverted rim and first mount the dropouts then close the whole thing! we hope well! pray for me!

yessssssssssss, I succeeded! the Ian method works! I turned Rumi with the wheels on top, and I reassembled the plate below after putting the dropouts for the selector! IT WORKS WELL !!!!!!!!!! THANK YOU REALLY THANK YOU! Thank IAN! thank you all!!!!!!!!!
